I want to use such checkbox instead of Yes/No select in magento 2 module configuration:

How can I achieve this? Maybe there is some tutorial?

If you mean from Store Configuration

Tutorial from here:

https://webkul.com/blog/create-checkbox-field-system-configuration-magento-2/

Webkul/DemoModule/etc/adminhtml/system.xml

<field id="checkbox" translate="label" sortOrder="350" showInDefault="1" showInWebsite="1" showInStore="0">
 <label>Checkbox</label>
 <frontend_model>WebkulDemoModuleBlockSystemConfigCheckbox</frontend_model>
</field>

Webkul/DemoModule/Block/System/Config/Checkbox.php

namespace WebkulDemoModuleBlockSystemConfig;

class Checkbox extends MagentoConfigBlockSystemConfigFormField

 const CONFIG_PATH = 'demomodule/group_id/checkbox';

 protected $_template = 'Webkul_DemoModule::system/config/checkbox.phtml';

 protected $_values = null;
 /**
 * @param MagentoBackendBlockTemplateContext $context
 * @param MagentoConfigModelConfigStructure $configStructure
 * @param array $data
 */
 public function __construct(
 MagentoBackendBlockTemplateContext $context,
 array $data = []
 ) 
 parent::__construct($context, $data);
 
 /**
 * Retrieve element HTML markup.
 *
 * @param MagentoFrameworkDataFormElementAbstractElement $element
 *
 * @return string
 */
 protected function _getElementHtml(MagentoFrameworkDataFormElementAbstractElement $element)
 
 $this->setNamePrefix($element->getName())
 ->setHtmlId($element->getHtmlId());

 return $this->_toHtml();
 

 public function getValues()
 
 $values = [];
 $objectManager = MagentoFrameworkAppObjectManager::getInstance();

 foreach ($objectManager->create('WebkulDemoModuleModelConfigSourceCheckbox')->toOptionArray() as $value) 
 $values[$value['value']] = $value['label'];
 

 return $values;
 
 /**
 * 
 * @param $name 
 * @return boolean
 */
 public function getIsChecked($name)
 
 return in_array($name, $this->getCheckedValues());
 
 /**
 * 
 *get the checked value from config
 */
 public function getCheckedValues()
 
 if (is_null($this->_values)) 
 $data = $this->getConfigData();
 if (isset($data[self::CONFIG_PATH])) 
 $data = $data[self::CONFIG_PATH];
 else 
 $data = '';
 
 $this->_values = explode(',', $data);
 

 return $this->_values;
 

Webkul/DemoModule/Model/Config/Source/Checkbox.php

namespace WebkulDemoModuleModelConfigSource;

/**
 * Used in creating options for getting product type value
 *
 */
class Checkbox

 /**
 * Options getter
 *
 * @return array
 */
 public function toOptionArray()
 
 return [['value' => 'checkbox', 'label'=>__('Checkbox')]];
 

Webkul/DemoModule/view/adminhtml/templates/system/config/checkbox.phtml

<input type="hidden" name="<?php echo $this->getNamePrefix() ?>" value="" /><!-- this is send if nothing is checked -->
<ul class="checkboxes">
 <?php foreach ($this->getValues() as $name => $label): ?>
 <li>
 <input type="checkbox" value="<?php echo $name?>" name="<?php echo $this->getNamePrefix() ?>[]" id="<?php echo $this->getHtmlId() . '_' . $name ?>"<?php echo ($this->getIsChecked($name) ? ' checked="checked"' : '') ?>/><label for="<?php echo $this->getHtmlId() . '_' . $name ?>">
 <?php echo $label ?>
 </label>
 </li>
 <?php endforeach;?>
</ul>

If you mean within a form
